As a human representative in the Galactic Empire's governing body, the Imperial Senate, Teenar held the position of senator. Following a rebel heist that occurred on the planet of Aldhani in 5 BBY, the Galactic Emperor, Sheev Palpatine, put forth the Public Order Resentencing Directive. Soon after this new law was proposed, Teenar was present at a gathering at the Chandrilan Embassy on the planet Coruscant, where the Chandrilan Senator Mon Mothma was working to secure votes against the directive.
While at the embassy, Teenar engaged in conversation with Mothma, Senators Vivyn and Dhow, along with a guest named Slorda, regarding the directive. Teenar, with the belief that the Empire had implemented limitless surveillance and prosecutions, remarked that Slorda's assessment of Palpatine as frustrating, overreactive, and easily provoked was an understatement. He also scoffed at Vivyn's suggestion that they were living in dangerous times. Teenar's physical appearance included tan skin, brown eyes, and gray hair. For the party, the senator chose to wear brown and yellow robes along with a matching hat.
